python - Python Tkinter，无法将图像打开到画布

Question

我正在尝试制作一个绘画应用程序，但我似乎无法将文件打开到画布。

from tkinter import *
from tkinter import colorchooser
from tkinter import filedialog
import os
import PIL
from PIL import Image, ImageDraw, ImageGrab, ImageTk

file = filedialog.askopenfilename(defaultextension = ".png",
                                      filetypes = [("All Files", "*.*"), ("Image File", ".png")])
if file is None:
    return
else:
    load = Image.open(file)
    render = ImageTk.PhotoImage(load)
    canvas.create_image(700,700, image=render)
